How to get curly quotes with Marked.js

November 30, 2020

Marked.js is a library for parsing Markdown into HTML.

I personally think that curly or “smart” quotes look better in writing, like this:

"straight quotes"
“curly quotes”
straight apostrophe: they're
curly apostrophe: they’re

To turn straight quotes into curly quotes when parsing with Marked.js, use the setOptions function to turn “smartypants” rendering on:

marked.setOptions({ smartypants: true });

marked.parse(/* markdown content */);

Now, marked.parse will produce HTML with intelligently replaced curly quotes.
